Minesweeper
🚩 10 flags left
Click to reveal. Right-click to flag. Reveal all non-mine cells to win. 9×9 grid with 10 mines. Numbers show adjacent mine count.
The classic Minesweeper game. A 9×9 grid contains 10 hidden mines. Click cells to reveal what’s underneath: a number showing how many of the 8 adjacent cells contain mines, an empty cell (auto- reveals all empty neighbors via flood-fill), or a mine (you lose, game over). Right-click to flag suspected mines visually. Reveal all non-mine cells to win.
Minesweeper has a remarkable history. The original (called “Mined-Out”) appeared on Personal Computer World magazine’s “Game of the Month” column in 1984. Robert Donner and Curt Johnson’s 1989 version shipped with Microsoft Windows 3.1 in 1992 and ran on every Windows install through Windows 7 (2009). Estimated 100s of millions of people learned basic mouse skills via this game — the right-click-to- flag mechanic was many users’ first encounter with multi-button mice.
The math is NP-complete in general (proven by Richard Kaye, 2000) — for arbitrary boards, deciding whether a position is solvable without guessing is as hard as the hardest computational problems. In practice, most positions on a 9×9 board are solvable deterministically (no guessing needed) once you’re past the opening flood-fill. Expert players solve a standard board in 30-100 seconds. The world-record times (under 1 second on Beginner mode) often involve sub-second mouse precision plus lucky opening boards.
Nasıl Kullanılır
- Left-click to reveal a cell. Numbers tell you how many mines are in the 8 adjacent cells (0 = empty, auto-reveals neighbors via flood-fill; 1-8 = number of adjacent mines).
- Right-click to flag a suspected mine. Flagged cells can't be revealed accidentally with left-click — useful as visual markers when you've deduced a mine location.
- Use the numbers to deduce safe cells: if a '1' has only one unrevealed neighbor, that neighbor is the mine. If a '1' is touching a flagged mine, all other unrevealed neighbors are safe.
- Reveal all non-mine cells to win. The game tracks elapsed time and flag count.
- If you hit a mine, the game ends — click New Game to start over.
Ne Zaman Kullanılır
- Classic 5-15 minute brain break for logical deduction.
- Demonstrating combinatorial reasoning to learners — Minesweeper is a natural proof-by-contradiction puzzle.
- Practicing focused attention — the time pressure plus careful deduction is a measurable cognitive workout.
- Casual nostalgia for users who learned PCs in the Windows 3.1 / 95 / 98 / XP / 7 era.
Ne Zaman Kullanılmaz
- When you have under 5 minutes — Minesweeper games rarely end quickly even for skilled players, and quitting mid-game is unsatisfying.
- If you find logical-deduction puzzles frustrating — some people genuinely don't enjoy them. Pick a different brain break.
- Multiplayer / collaborative — Minesweeper is single-player by design.
Yaygın Kullanım Senaryoları
- Onboarding a colleague who needs the same calculation/conversion
- Verifying a number or output before passing it on
- Quick use during a typical workday
- Pre-decision sanity-check on inputs and outputs
Sık Sorulan Sorular
Why does the first click sometimes hit a mine?
Microsoft's Minesweeper (and most modern implementations) guarantee the first click is safe — they re-place mines if needed. This implementation currently doesn't have that guarantee — if you hit a mine on click 1, click New Game and try again. Fixing this is a small change we'll add in a future update.
Is Minesweeper actually solvable without guessing?
Sometimes, sometimes not. On expert (16×30 board with 99 mines), about 30-40% of games eventually require a guess at some point — there's a position where the available numbers can't deterministically identify a safe cell. World-record players accept the guess and play the probability. On smaller boards (9×9 beginner), most games can be solved deterministically.
What's the world record?
Beginner (9×9, 10 mines): under 1 second (yes, some players are that fast — assisted by lucky opening flood-fills). Intermediate (16×16, 40 mines): ~7 seconds. Expert (16×30, 99 mines): ~30 seconds. Records are tracked at minesweeper.info; verification involves video review of mouse movements to detect cheating.
How do I flag mines?
Right-click any unrevealed cell to flag it as suspected mine. Right-click again to remove the flag. Flagged cells display a flag icon and can't be left-clicked (saves you from accidentally revealing a mine you've already identified).
Why is Minesweeper NP-complete?
Richard Kaye proved in 2000 that determining whether a partially-revealed Minesweeper board is consistent (i.e. there's a valid mine placement matching the visible numbers) is NP-complete. Practically: for some boards, you'd need exponential time to guarantee no-guess-required play. This is why expert tactics include 'efficiency moves' that gather information cheaply rather than trying to solve specific cells deterministically.
Are there variants?
Many: Hexagonal Minesweeper (hex grid), 3D Minesweeper (cube of cells), Mosaic / Fillomino (logical puzzles inspired by Minesweeper), Mines+Numbers blends. The version here is classic Microsoft 9×9 with 10 mines (Beginner difficulty in MS Minesweeper).
